A great thanks for your response.You may not beleive it : i saw your 2 answers - when i put this one(def init(self): ,, it says wrong syntax showing the : symbol ,, and when i put this one( def init(self): ) with no indents as your answer ,, it says to me : did you put the pass keyword into the body of init()? make sure you indent correcty . i'm very confused , again thanks a lot
